In this construction video tutorial, you will be familiar with the brief procedure for determining the slope of the stair.

Slope in a staircase means the ratio among the rise and run or the ratio of change in height to change in horizontal distance.

Normally, the slope is 7-11 (a 7 inch rise and 11 inch run). More specifically, it can be said not in excess of 7 3/4 inches for the riser (vertical) and at least 10 inches for the tread (horizontal or step).

To know the details calculation process for slope, go through the following video tutorial.
